A couple of weeks ago a man came up as a suggested friend on Facebook, I don't know him and we don't have any mutual friends but I can't stop thinking about him. Last week he popped up on a dating site but he hadn't been on their for a month. I messaged him not expecting a reply as I came to realise this site is a con, sends out fake messages etc so can see why he hasn't been on there. I didn't get a reply but I could see he hadn't been back on there. My question is should I message him on Facebook? I don't usually message strange men lol and what would I even say?
